Thanks for posting this. Have you tried these with a slower film like FP4 or Pan F?
I did some test with a CD too. Ortho Phenylene Diamine like in the W665 formulae. However here you have a speed loss of 1F stop. But the result is very fine grain. The interesting about your A49 and Ascorbate is the film speed: Still E.I. 400 with that HP5+ ?
Fomapan Creative 200 (135-36) in W665 E.I. 100
With hydroquinone it may be like Adox Adolux ATM 49 but interesting to see that it works with ascorbate as well.It would be interesting to know your formula.
Sodium Sulfite 60g
Sodium Ascorbate 5g
Sodium Sulfite 100g
Boric Acid 4g
no. but I think that result will be very-very good

It seems the new name for the commercial product is Adox Atomal 49:
It is available in the US EU and UK at least.
You made a good piece of research but CD-1 is not available everywhere.
btw the msds for ATM 49 appears different from the original Atomal formula which is as quoted in this thread:

N-Hydroxyethyl-o-aminophenol used in original Atomal isn't available anywhere.

Calbe A-49 uses as developing agents:
N-N-diethyl-1,4-phenylendiammoniumsulfate = Kodak CD1 and
CD-1 can be substituted (and I really substitute it) with N,N-Diethyl-p-phenylenediamine Hydrochloride, CAS: 2198-58-5 (also available).
CD-1 also can changed to CD-2 - N, N-bis (2-hydroxyethyl)-p-phenylene diamine Sulfate (CAS: 4327-84-8), but CD-2 need in 1.5-1.8 times more
you can try to use CD-3 or CD-4. can't test it because not available in my country
One day it would be an interesting experiment to try to make something like original Atomal ,replacing oxyethyl o aminophenol by p-aminophenol hydrochloride,maybe.
